- BACKGROUND: Mean left atrioventricular plane displacement is strongly related to prognosis in patients with heart failure. We aimed to examine its value for prognostication and risk stratification in patients hospitalised for acute myocardial infarction. METHODS AND RESULTS: Left atrioventricular plane displacement was assessed by echocardiography in 271 consecutive patients with acute myocardial infarction. Mean prospective follow-up was 628 days. Atrioventricular plane displacement was readily assessed in all patients and was significantly lower in patients who died (n=41, 15.1%) compared to the survivors: 8.2(5.6) v. 10.0(5.5) mm, P<0.0001. Overall mortality was 31.3% in the lowest quartile with regard to atrioventricular plane displacement (<8.00 mm) and 10.1% in the combined upper three quartiles. Thus, the hazard ratio for an atrioventricular plane displacement <8.0 mm compared to 8 mm or more was 3.1, P=0.0001. The combined mortality/heart failure hospitalisation incidence was 43.8% in the lowest and 14.6% in the combined upper three quartiles: Risk ratio 3.0, P<0.0001. In multivariate analysis, including age and history of atrial fibrillation, left atrioventricular plane displacement was an independent prognostic marker. CONCLUSION: In post-myocardial infarction patients, echocardiographic assessment of atrioventricular plane displacement showed a strong, independent prognostic value. Determination of left atrioventricular plane displacement can be readily performed in virtually all patients, and may in clinical practice facilitate identification of high-risk patients.

- Background: Erectile dysfunction is associated with, and may be the first sign of coronary artery disease. We aimed to assess whether men with erectile dysfunction but without cardiovascular disease have reduced coronary flow reserve, as a sign of early coronary atherosclerosis. Methods: We investigated 12 men aged 68-73 years with erectile dysfunction, and 12 age-matched controls. Erectile function was evaluated using the validated IIEF-5 questionnaire. A score <= 18 (of 25) was defined as erectile dysfunction and >= 21 was considered non-nal. Patients with neurological or psychological reasons for erectile dysfunction were excluded, as were patients with symptoms of or prescribed medication for cardiovascular disease, hypertension or diabetes. Coronary flow velocity reserve was measured non-invasively by Doppler in the left anterior descending artery, before and during adenosine infusion. Results: Coronary flow velocity reserve was significantly reduced in subjects with erectile dysfunction: 2.36 versus 3.19; P=0.024. In logistic regression analysis, compared to control subjects, men with erectile dysfunction had significantly increased risk of reduced coronary flow velocity reserve (<= 3.0): odds ratio 15.4, P = 0.02. In multivariate analysis, adjusting for age, tobacco use, systolic blood pressure, heart rate and body mass index, erectile dysfunction was the only significant predictor of reduced coronary flow velocity reserve, P=0.016. Conclusions: Men with erectile dysfunction but without diabetes or clinical cardiovascular disease have early signs of coronary artery disease. Our findings suggest that a cardiac risk evaluation may be indicated in men with suspected vasculogenic erectile dysfunction, and these individuals should be considered for primary prevention measures regarding cardiovascular disease risk factors.

- Background: The frequency and prognostic importance of atrial fibrillation (AF) in asymptomatic mild-to-moderate aortic stenosis (AS) has not been well described. Methods: Clinical examination, electrocardiography and echocardiography were obtained in asymptomatic patients with mild-to-moderate AS and preserved left ventricular (LV) systolic function, randomized to simvastatin/ezetimibe combination vs. placebo in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study. At inclusion, AF was categorized as episodic or longstanding. Rhythm change was assessed on annual in-study electrocardiograms. Impact of AF on cardiovascular morbidity and mortality was determined by adjusting for biomarkers, clinical- and echocardiographic covariates. Results: Mean follow-up was 4.3 +/- 0.8 years (6,721 patient-years of follow-up). At baseline, episodic AF was present in 87 patients (5.6%), longstanding AF in 55 (3.5%) and no AF in 1,421 (90.9%). Incidence of new-onset AF was 1.2%/year; highest in those with impaired LV function. In multivariable analysis, longstanding AF was compared to no AF at baseline, associated with a 4.1-fold higher risk of heart failure (CI 1.2 to 13.8, p = 0.02) and a 4.8-fold higher risk of non-hemorrhagic stroke (CI 1.7 to 13.6, p = 0.003). Conclusion: Rate of AF is moderate in asymptomatic AS. Longstanding but not episodic AF was, independently predictive of increased risk of heart failure and non-hemorrhagic stroke. New-onset AF was associated with cardiac decompensation. (c) 2011 Elsevier Ireland Ltd. All rights reserved.

- The prognostic impact of body mass index ( BMI) in patients following acute myocardial infarction ( AMI) may be altered by neurohormonal blockade. Methods: The impact of neurohormonal blockade on the association between BMI and mortality was examined in 5548 patients following AMI ( CONSENSUS II), 50% receiving enalapril and 7% beta- blockade, and in 4367 patients with coronary artery disease ( CAD) ( 4S), 79% with prior AMI, 12% receiving ACEi and 67% beta- blockade. Median follow- up was 0.4 and 5.2 years, respectively. Patients were categorized into 4 BMI groups: Underweight, b22.00; normal- weight, 22.00 - 24.99; overweight, 25.00 - 29.99; obese, = 30.00 kg/ m(2). Multivariable analysis adjusted for demographics, patient history, physical examination, biochemistry and medication. Results: CONSENSUS II: Overall, adjusted mortality ( n= 301) risk was similar across BMI groups. Comparing overweight with normalweight patients, the hazard ratios ( HRs) for mortality differed significantly ( P= 0.028) between patients randomized to placebo ( HR 1.41) and enalapril ( HR 0.75). 4S: Overall, adjusted mortality ( n= 421) risk was similar for normal- weight, overweight and obese patients. In a time- dependent analysis for drug use, comparing obese with normal- weight patients, the HRs for mortality differed significantly ( P= 0.047) between patients without ( HR 1.86) and those with ( HR 0.97) neurohormonal blockade. Conclusion: In patients after AMI or with CAD, high BMI was associated with increased mortality risk among patients not receiving neurohormonal blockade, but with decreased or neutral mortality risk among those receiving neurohormonal blockade. Tests for interaction indicate that neurohormonal blockade may attenuate the relationship between high BMI and increased mortality risk. Neurohormonal blockade may thus partly explain the so- called obesity paradox. (C) 2006 Elsevier Ireland Ltd. All rights reserved.

- OBJECTIVE: The pathogenesis of hypertension in patients with primary hyperparathyroidism (PHPT) is unclear, and the prevailing opinion is that parathyroidectomy does not affect the blood pressure (BP). Most previous studies have been based on BP measurements at rest in a clinical setting. The aim of this study was to get additional information by 24-hour ambulatory measurements. DESIGN AND PATIENTS: Forty-nine consecutive patients with PHPT (age 63+/-12 years, 44 women) were examined before and 6 months after curative parathyroid surgery. MEASUREMENTS: Serum concentrations of calcium and PTH, and 24-hour ambulatory mean, minimum, and maximum systolic (S) and diastolic BP, and mean arterial BP. RESULTS: On average, the patients showed no BP change after parathyroidectomy. However, those with a history of hypertension (n=20) showed generally increased BP values after parathyroidectomy, with significantly increased minimum and average SBP (P=0.02 and P=0.04, respectively), whereas patients without a history of hypertension (n=29) showed unchanged or slightly reduced BP values after parathyroidectomy, with significantly decreased maximum SBP (P=0.04). Serum concentrations of PTH and calcium were not significantly related to any of the BP variables measured. CONCLUSIONS: The novel finding that patients with both PHPT and hypertension may show increased BP after parathyroidectomy warrants intensified BP control postoperatively in these patients, and motivates early treatment of PHPT in order to prevent the development of complicating hypertension.

- AIM AND METHODS: We assessed gender differences in variables related to B-natriuretic peptide (BNP), left ventricular ejection fraction (LVEF), peak oxygen consumption (peak-VO2), and LV mass (LVM), among patients recently hospitalized for suspected heart failure (HF). RESULTS: Of 930 consecutive patients, 409 accepted follow-up after discharge, 221 of these had definite HF (90 women, mean age 74.5 [9.8]years). In 141 HF patients (61 women) with BNP data, women had lower BNP than men (43.9 [38.1] versus 76.3 [88.9]pmol/L, P=0.0193). LVEF (all HF patients) was higher in women (49.8 [13.4] versus 42.4 [13.9]%, P=0.0004). Peak-VO2 (147 HF patients, 48 women) was lower in women (13.9 [4.3] versus 16.3 [4.2]mL/kg/min, P=0.0093). LVM index (200 HF patients, 78 women) was lower in women (130.4 [46.5] versus 171.7 [57.6]g/m(2), P<0.0001). Among HF patients, variables independently related to BNP were body mass index (BMI) and peak-VO2 exclusively among men, mitral regurgitation, respiratory disease and angiotensin receptor blocker treatment only among women. Variables independently related to LVEF were resting heart rate, acetylic salicylic acid use and BNP exclusively among men. No variable was exclusive for women. Variables independently related to peak-VO2 were right ventricular size, BNP, resting and peak heart rate solely among men, BMI and stable angina pectoris exclusively among women. Variables independently related to LVM were left atrial diameter only among men, BMI exclusively among women. CONCLUSION: Among elderly HF patients, there were some important gender differences in BNP, LVEF, peak-VO2 and LVM, and in variables independently related to these factors.

- Background: In CIBIS III, initiating chronic heart failure (CHF) treatment with bisoprolol (target dose 10 mg q.d.) followed by combination therapy with enalapril (target dose 10 mg b.i.d.), compared to the opposite order, showed similar effects on survival and hospitalization. By echocardiography, we evaluated the effects of these treatment strategies on cardiac structure and function. Methods: In a single-centre substudy, we compared the impact on left ventricular (LV) dimensions and ejection fraction (EF) of treatment with bisoprolol-first (n = 21) and enalapril-first (n = 19) in 40 beta-blocker and angiotensin-converting-enzyme-inhibitor naive patients, with stable, mild or moderate CHF (NYHA II-III) and LVEF <= 35%. Echocardiography was performed at baseline, after the 6-month monotherapy phase and after 12 months, i.e. after 6 months combination therapy. Results: Baseline characteristics were similar across treatment groups. After 6 months LVEF increased by 5.1 +/- 4.0 EF-% (P<0.0001) with Bisoprolol and 4.0 +/- 4.0 EF-% (P = 0.0005), with enalapril (between-group P = 0.47). LV end-diastolic volume (LVEDV) decreased by 8.1 +/- 4.7 ml (P<0.0001) with bisoprolol and by 4.6 +/- 8.2 ml (P = 0.03) with enalapril (between-group P = 0.16). Mean wall thickness (WT) decreased by 0.31 +/- 0.43 mm (P = 0.004) with bisoprolol and by 0.18 +/- 0.48 mm (P = 0.11) with enalapril (between-group P = 0.29). From baseline to 12 months, LVEF increased by 7.5 +/- 4.0 EF-% (P<0.0001) in Bisoprolol first group and 6.0 +/- 4.6 EF-% (P<0.0001), in the enalapril first group (between-group P = 0.31). LVEDV decreased by 12.9 +/- 6.3 ml (P<0.0001) with bisoprolol-first and by 7.9 +/- 7.7 ml (P = 0.0006) with enalapril-first (between-group P = 0.16) and WT decreased by 0.38 +/- 0.44 mm (P = 0.0008) and 0.59 +/- 0.54 mm (P = 0.0004), respectively (between-group P = 0.10). Conclusion: During both monotherapy and combined therapy, bisoprolol-first and enalapril-first similarly reversed cardiac remodelling and improved LVEF. (C) 2009 Elsevier Ireland Ltd.
